IMPROVEMENT-IN PACKINGS FOR STEAM-ENGINES, GAS-PIPES, WATER-PIPES, 8w.

Specification forming part of Letters Patent No. 120,003, dated October17,1871.

To all whom it may concern:

Be it known that I, ALONZO J. Snvnvrons, of Indianapolis, county ofMarion and State of In diana, have invented certain Improvements inSteam, Hydraulic, and Gas-Packing, of which the following is aspecification:

The object of this invention is to make a packing which, While verycheap and durable, is efficient as a steam, hydraulic or gas-packing.The nature of the invention consists in manufactun ing or preparing acompound of sawdust, tallow, plumbago, and spermaceti for use in asteam, hydraulic, and gas-packing, as is hereinafter more fullydescribed and set forth.

To prepare my said packing take eight (8) parts sawdust, two (2) tallow,and (1) part spermaceti and heat or bake the same until the sawdust iswell charred and thoroughly impregnated with the oils. While heating,the above compound should be Well stirred in order that the sawdust maybe evenly and well charred. After the sawdust is sufficiently charred orbaked take two parts plumbago and mix it thoroughly with the otheringredients while they are still warm. When thoroughly mixed press thecompound in any convenient press until nearly all of the oils arepressed out. It is then ready for use.

My said packing is to be used as any other ordinary packing. When usedas a steam-packing, for which it is Well adapted, it will be found upontrial that the action of the piston upon my said packing will form aperfectly smooth or enameled surface; therefore there is very little orno friction, and that it will prevent the escape of steam much moreeffectually than any other known packing. Also, that it is much moredurable and easier to retain in its proper position, as after my saidpacking becomes well set it Wi ll retain its posit-ion and Workeffectually even after the compression of the gland has been removed. Mysaid packing is especially adapted for use as gas-packing, as thechemical action of the ammonia, which is so injurious to ordinarypacking, has but little or no effect upon its composition, and for thatreason it is more durable and cheaper than ordinary packing.

I claim as my invention, and desire to secure by Letters Patent Themanufacture or preparation of a compound to be used as steam, hydraulic,or gas-paokin g, of the ingredients in the proportions, and for thepurposes set forth.

In testimony that I claim the foregoing as mine I hereto set my handthis 20th day of July, 1871.

ALONZO J. SIMMONS.
